Specification of Letters Patent.

Application filed May. 27, 1915. Serial No. 30,712.

To all whom it may concern:

Be it known that I, J UDSON L. MCKELLAR, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bedsteads, of which the following is a specification. 7

The invention pertains more particularly to a novel spring composedof separate units adapted to be applied to bedsteads whether of the metal variety or made of wood. The spring units of my invention when applied to metal bedsteads will be suspended upon the side rails thereof by means of suitable arms carried by said units, and when said spring units are applied to wooden bedsteads they will be placed directly upon the slats thereof. The spring units of my invention will vary in size in accordance with the size of the bedstead frame to which they may be applied, and ordinarily it will be found convenient to have said units of such three thereof will be suflicient for a bedstead of the usual length. By making the spring in units or sections, a very strong and durable .bed spring structure may be formed, and in addition the separate units by beingof durable character may be handled, shipped and moved about with convenience and without special danger of becoming injured. The spring units of my invention will be detachably applied to bedsteads, and when so applied will receive the mattress in the usual Way.

The invention will befully understood from the detailed description hereinafter presented, reference being had to the ac companying drawings, in which:

Figure 1 is a top view'of a portion of a bedstead equipped with spring units emodying my invention;

Fig. 2 is a sectional view on a larger scale and partly broken away, through the same taken on the dotted line 2 -2 of Fig. 1, and

Fig. 3 is a side elevation of a small portion of the bedstead frame and of one of the spring units of my invention.

In the drawings, 10 designates the side rails of a metal bedstead of usual character, and 11 one of the end frames thereof and to which the side rails are connected in the customary manner.

The spring units of my invention are numbered, as awhole, 12 and are detachably supported upon the side rails 10. Each unit 12 is composed of an upper wire structure comprising a rectangular frame 13 of reasonably heavy wire and longitudinal and transverse wires lirunning at right angles to each other and connected at their ends to the frame 13 and affording a support for the usual mattress, not shown. The crossed wires 14 are connected with the upper ends of a series of coiled wire springs 15 of usual character and these springs are secured at their lower ends to a lower frame structure constituting the base of the unit and formed of angle side bars 16, angle end bars 17 and transverse bars 18 which are flat and bent angularly at their ends and riveted to the side bars 16. The bars 16, 17 are riveted together at their ends and the bars 18 are connected together in pairs by short longitudinal bars 19 which present a fiat upper surface, as shown in Fig. 2, and are bent downwardly at their ends and riveted to the bars 18. The lower structure comprising the bars 16, 17, 18 and 19 present a rigid frame and this frame is further strengthened by a central longitudinal wire rod 20 which connects the end bars 17 and extends through the bars 18. The coiled springs 15 are connected at their lower ends to the transverse bars 18, said bars 18 being slit to receive the lower coil of said springs.

Upon the short longitudinal bars 19 are pivotally mounted the bracket arms 21, there being two of these bracket arms at each side of the lower frame structure of the unit. The bracket arms 21 are slotted at their inner ends, as at 22, so that they may be adjusted laterally on the rivets 23 securing them to the bars 19, this lateral adjustment being desirable in adapting the units to beds varying in width. The outer ends of the arms 21 extend upwardly, outwardly and downwardly to form box loops or hooks 24 adapted to engage the upper portions of the side rails 10 of the bedstead frame and thereby suspend the unit in said frame. The angle side bars 16 of the lower structure of the unit have secured to them metal plates 25 which extend upwardly and are formed with longitudinally extending members 26 between which and the bars 16, the bracket arms 21, when in operative position, extend, said members 26 serving to hold the outer portions of the arms 21 close down. upon the wid he bed ead f ame might be placedupon the bed. The rivets 23 alone would hardly be'stulicient to-sus tain the arms 21 111 the actual use of the bed. unit, and hence I have provided the plates 25 which serve to holdthe a1'ms21 rigidly,

bars 16"and resist any tendency of th@ '-&I- I'11S"12l :tcbend down-upon or close to the side upwardly at their outer portions. The bracket arms are latellally adjustable :as aioresaidso thattheir hookanembeirs -24 assuredly engagetheside rails lOevemthoU h thereernay be some slightyariations in te to which the units n aybe applied; The rivets .23 hold the bracket arms 21 with suflicient freedom to permit cf the lateral adj tment of said arms: and also to: allow said, arms .to be turned inwardly in Y line with the longitudinal bars l9'bclow the upper strl ctllre of the unit. When the units are kept ,il'l;$1}OOk-QI are t be shipped, it is desirable that the bracket arms 21' be turned inwardly ..out of t y- Th Me -hanging members 26 0fthe plates-25ipe mit the bracket-arms 21 110 beturned under as will be read y u dersto QI re e emie to Figs 2 and It is aleodesirablthat the bracket armsfzl be --eapa1clepf being turned inwardl-y cut of the way when the e unit are-to be u e up n a Wcocleabed, beicau e; in t t se: o he u its. the lower frame structure thereof may be setdirectly upon-the usual bed slate, and since" when the units are supported ion-:the-bed slats it is not necessary that the bracket-arms-be:
